Xu Que knew that he carried many flaws from his family of origin, but no one in this world is without hurt and pain; everyone is covered in wounds and carrying heavy burdens as they move forward!

He blamed no one for any of this. From another perspective, his parents also came from their own families of origin; who could they turn to for justice? In the memories of most Easterners, home is the deepest scar and the most profound attachment! Lucky people use their childhood to heal their entire lives; unlucky people spend their entire lives healing from their childhood! Xu Que planned to spend his life healing his childhood in this primitive tribe!

Inside the cave of the Black Stone Tribe, Hou's coughs and waves of pressure silently pulled Xu Que's thoughts, which had drifted to the modern city, back to reality.

Bored, Xu Que opened his exchange shop in the dark, and his exchange coins had quietly risen back to 1500. Although he had previously bought a large iron pot for the Black Stone Tribe, the system had also rewarded him with a considerable amount of exchange coins for his interactions with Hou these past few days.

Xu Que looked at the beautiful and exquisite porcelain bowls with floral patterns and chopsticks carved with dragons and phoenixes in the exchange shop, wondering if he should get a set for everyone in the tribe.

But considering that primitive people in tribes mainly rely on gnawing, even if each person were given a set of bowls and chopsticks, they would still end up smashing the bowls and throwing away the chopsticks!

In order to save enough exchange coins to exchange for the most urgently needed items, Xu Que decided not to exchange them for anything! They've been living off others for most of their lives, so there's no rush.

Xu Que felt that teaching the church members how to make pottery was much more meaningful than simply giving them bowls.

The system's redemption shop has been updated with a variety of new items. Bandages, hemostatic forceps, disinfectant, table salt, maintenance-free automatic saws, sugar, bottled adrenaline, women's underwear, sneakers—all sorts of medicines and daily necessities are available! Unfortunately, the redemption rules are the same as before: these items can only be redeemed once, not infinitely!

This shows that the system was designed solely for Xu Que. Any purchase is made in a single, exclusive quantity, without considering other members of the tribe or requiring additional purchases. It only needs to ensure Xu Que has enough, which aligns with the system's initial design. From a long-term perspective, this approach better protects user privacy and lays the foundation for future upgrades and power enhancements. It must be said that the system is quite user-friendly in this respect!

In the primitive tribe, the nights were inexplicably long. Since he couldn't sleep anyway, Xu Que continued to scroll down the pages of the system's exchange shop.

As he flipped through the pages, he stumbled upon a treasure: a powerful-looking off-road motorcycle gleaming with blue light, the Thunder Shield Flying Lightning. This was a type of item he'd only ever dreamed of in his past life; its appearance in the exchange shop astounded Xu Que.

Xu Que's eyes suddenly lit up. He looked at the three views of the device from all angles, back and forth, up and down, left and right. He really liked it! He then flipped down a little to check the exchange rate of the currency it required.

Xu Que was dumbfounded; he needed to exchange currency.

"My goodness! How many years would it take to accumulate enough exchange coins!" Xu Que swallowed a couple of times, slightly disappointed, and continued to learn about its other attributes.

The specifications for Thunder Shield Flying Lightning are as follows: Name: Thunder Shield Flying Lightning. Displacement: None.

(∞) Engine: True Thunder Shield multi-cylinder direct-crack element-cooled eight-valve asynchronous engine. Transmission: Meteorite cast iron chain. Power/Speed: 300,000 km/h, speed can be set at will...

After seeing the parameter that the Thunder Shield Flying Lightning could exceed the speed of light, Xu Que lost interest in understanding the other parameters.

"This speed can exceed the speed of light, isn't that like a portable time machine? This is too powerful!" Xu Que couldn't help but wonder: Since this system shop can display such bizarre products as Thunder Shield·Flying Lightning, does it mean that this shop is connected to one or more civilizations of higher dimensions?" Thinking of this, Xu Que scratched his head and pondered for a while, not daring to think further along this line of thought.

But curiosity led him to search the entire page of the system's exchange shop for evidence that could support his conjecture.

Sure enough, after flipping to the eighth page, starting from the ninth page, all the items in the store began to become bizarre and unbelievable: causal bombs, two-dimensional foils, Ruyi Jingu Bang (the magic staff), life-extending pills, and other items appeared in the exchange store, but these items were marked with the words "Price not yet available" and the entire product was grayed out and could not be purchased or exchanged!

After being shocked by the above-mentioned products, Xu Que began to take things seriously: "Since there is the Ruyi Jingu Bang, let me see if there is Laozi's alchemy furnace, and while I'm at it, I'll get a couple of elixir pills to strengthen my body and replenish my kidneys! I've been so tired from being yelled at these past few days, my back aches, my eyes are blurry, and my knees are weak. I feel like my body has been hollowed out, and I suspect I have kidney deficiency!"

He searched for a long time but couldn't find the alchemy furnace. Instead, he found Liuwei Dihuang Pills and loose goji berries in the store's automatic push link.

Xu Que had no choice but to give up and continue flipping through the pages. He found that the further he flipped, the more bizarre the products appeared in the system's exchange shop. However, all of these bizarre products were displayed in gray, indicating that they could not be activated for exchange or purchase.

At this moment, Xu Que had a clue. He was quite certain that his system's exchange shop was connected to, or even linked to, more than one high-dimensional civilization in some aspects.

Xu Que calmed down and thought about it. It wasn't surprising at all. The system itself was a product of a higher-dimensional civilization, so it was perfectly normal for this product to connect with a higher-dimensional civilization! He was only surprised because he hadn't seen much of this before!

I've been busy with this and that in the Blackrock Tribe lately, busy with dating and such, and haven't had time to browse this portable system exchange shop. These items have been there since the first day the system was activated, so there's nothing to be surprised about!

Xu Que continued flipping through the pages, and as he did, an ancient suit of armor, shimmering with purple light, appeared before him like a bonus from the in-game store. A countdown timer appeared beneath the cool armor, indicating its disappearance. The exchange rate for the new currency was now displayed with a red diagonal line, showing a price of only 1 exchange coin.

"I'm speechless about this system shop! Can't I have something I want? What use is this armor to me? I think it's too expensive for one exchange coin! And it's an extra-large size! If you're so capable, why don't you get a Thunder Shield Flying Lightning?" Xu Que complained inwardly as he continued to examine the armor that could be obtained for only one exchange coin.

Xu Que didn't immediately scroll away to the next page because exchanging it only cost 1 coin, which was practically free.

Xu Que had been browsing the system's exchange shop for ages without getting a single item, and he felt like he'd missed out! He'd been looking around for so long, he should at least try to get something out of it!

The item details describe this armor as follows: True Emperor Armor. The ultimate armor of a first-level cosmic civilization, possessing dual attributes of armor beast enhancement and the Light Emperor War Dragon enhancement. The Emperor Armor's power originates from the wearer, and its power is theoretically set to be infinitely powerful. If the wearer is too weak, the armor is almost useless! In short, to sum it up in one sentence: It becomes stronger against strong opponents and weaker against weak opponents!

"Oh no! How could I forget about Hagang! This is perfect for him! According to the armor's description, Hagang is very strong, so wearing it will probably allow him to unleash even greater power!" Thinking this, Xu Que immediately pocketed the exchange coin, planning to give it to Hagang at dawn!

He finally yawned, staring at the endless pages of the exchange shop, muttering as he scrolled back, "I think I'll stop scrolling! There are just too many to scroll through!"

When he flipped to the daily necessities section, he stopped, subconsciously turned his head to look at it, and then clicked on the women's underwear and panties in the redemption shop.

"How do I choose the right bra size?" Xu Que scratched his head, at a loss.

With the intention of finding a measurement method, he clicked into the details page to see if there were any simple and convenient measurement guides.

A cup: A cup size suitable for women with small breasts. It can shape the breasts well and make them look less flat.

B cup: This is the most common bra size among East Asian women and falls within the normal range of breast size.

C cup: For this cup size, it's important to choose the right bra size to avoid breasts spreading outwards or sagging, which would affect the appearance.

D cup: This size is a bit too big and is easily troubled by sagging. Therefore, D cup bras mainly focus on support.

Looking at the bra size descriptions in the system's redemption shop, Xu Que fell into deep thought: "I haven't really paid much attention to it before, but based on my memories of daily life, it shouldn't be too big! But it's not small either! It's not a D cup! So it should be a C cup!"

Xu Que exchanged it for 10 exchange coins. He also exchanged it for a pair of white sneakers in size 44.
